4.1 Basic technique


Basic cutting techniques


Get a grip on your cutting

  • Hold the rear handle with your right hand and the front handle with your left hand. Keep a firm grip with thumbs and fingers encircling both handles.
  • Adjust the blade guard so that the rear section is flush with the work piece. This is to protect you from spatter and sparks.
  • Before you start cutting, always make sure that you have good balance and a firm foothold.
Basic cutting techniques


Applying the cut

  • Important! For ergonomic and safety reasons, never cut above shoulder height. Stand on a scaffold or a platform (never a ladder) to make high cuts.
  • Apply the cutting blade gently at full throttle and maintain full speed until you’re finished.
  • To avoid injury if a kickback occurs, stand parallel to the cutting blade (instead of directly behind it).
Basic cutting techniques


Stay safe

  • Always maintain a safe distance from the blade when the engine is running.
  • Never force the machine or press the blade. Always cut straight. Pressure from the side can damage the blade and be potentially dangerous.

4.2 Operational safety


A kickback is the sudden upward motion of the power cutter that can occur if you stall the blade in the wrong way. Another hazardous situation is when the blade is being pinched. Watch the video above or read about how to minimise the risk of kickbacks and pinched blades.

4.3 Horizontal, vertical & pipe cutting


How to cut - cutting techniques

Horizontal & vertical cutting

4 WA20

Cutting with the help of WA20

Here’s how to make horizontal and vertical cuts as well as cutting pipes. Watch the video to the right or read the instructions below.

Horizontal cutting

  1. To start with, mark where you should cut.
  2. To cut horizontally, start by making a guide cut approximately 2 cm deep. Cut from left to right, to have a clear view of the cutting line.
  3. Then go deeper, using step cutting, approximately 5 cm deep at a time.

Vertical cutting

  1. To cut vertically, start by making a guide cut approximately 2 cm deep. Cut from the bottom to the top, to have a clear view of the cutting line.
  2. Then go deeper, using step cutting, approximately 5 cm deep at a time. Cut from the top to the bottom. Always maintain full speed for best cutting performance.

Cutting with WA20

WA20 is a safe and effective way to cut straight in walls and floor. With the WA20 your powercutter transform into a small wallsaw. Attach the rail to the wall, attach the machine to the carrige and start cutting. The carrige has a manual brake that keep the carrige in place while attaching the machine.

 

4.4 Pipe cutting


4 Pipe Cutting

Pipe cutting

Here’s how to cut a pipe, with or without the pipe clamp.

Pipe cutting

1. To cut a pipe, start by cutting the top.
2. Then cut one side of the pipe from the top to the bottom.
3. Move to the other side and cut the remaining part of the pipe, from the top to the bottom.

4 PIPECLAMP

Cutting with the pipe clamp

The pipe clamp accessory is the best way to cut pipes straight and in a safe way. 
Making the whole cut from above means less need for digging around the pipe, 
which saves a lot of working time and effort.

4.5 Wet & dry cutting


Wet cutting

4 Wet Cutting

We recommend you to use water where possible. Wet cutting is better for you as an operator, the surrounding environment and the machine.

Dry cutting

4 Dry Cutting

We recommend that you use dry cutting for only a short period at a time. The reason for this is, that a dry cutting diamond blade needs to cool down occasionally to keep from being over heated and damaged.

KV

5 KV

KV7 & KV9/12 are cutting trolleys for the standard power cutters K 770, K 970 & K 1270 that makes the floor cutting safer and less strainful. Quick connections makes it easy and fast to switch between hand held and trolley operation. Adjustible cutting depth and water pressure tank are some of the features this versatile trolley holds.

Wheel kit

4 WheelKit

A wheel kit attached to your power cutter is a way to relieve strain when cutting in walls and floor. This accessory also protect the underside of the machine from scratches and dents. The wheel kit comes with integrated parking pads that prevents the machine from start rolling when placed on the ground. The wheel kit fits K 760/K 770/K 970/K 1270 and K 6500

4.8 Blade problems & blade sharpening


Stay sharp with blades in great condition

When blade problems occur they are often caused by the wrong blade being used f or the wrong job, the blade being used incorrectly or if there’s an equipment fault. Here are some examples of blade problems:

Loss of tension

Loss of tension.

Some possible causes: the blade is too hard in relation to the material being cut or the blade is used at the wrong speed of rotation. Recommendation: change the blade.

Eccentricity

Eccentricity.

Some possible causes: the bond is too hard for the material being cut or the spindle bearings are worn. Recommendation: change the blade.

Glazed blade

Glazed.

Possible cause: the blade hasn’t had adequate pressure when placed against the material being cut. Recommendation: sharpen the blade.

Cracked centre plate

Cracked centre plate.

Some possible causes: cutting pressure is too high or the blade has overheated due to inadequate water supply. Recommendation: change the blade.

Cracked segment

Cracked segment.

Possible causes: the blade is too hard for the material being cut or the cutting speed is too fast. Recommendation: change the blade.

Regain sharpness

A diamond blade can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete. To sharpen the blade, cut in a soft material such as sandstone or a brick.
